A simple pendulum of length (10)/(3) meter with a bob of mass 3 m is hanging freely from a rigid support. A bullet of mass .m. is fired with a velocity 50ms^(-1) from the ground at an angle .theta. with the horizontal. When the bullet is at its highest point of its trajectory, it collides head on with the bob of the pendulum and gets embeded in the bob. After collision, if the pendulum moves through a maximum angleof 120^(@), then the value of .theta. is (g = 10ms^(-2))

1.	A simple pendulum of length (10)/(3) meter with a bob of mass 3 m is hanging freely from a rigid support. A bullet of mass .m. is fired with a velocity 50ms^(-1) from the ground at an angle .theta. with the horizontal. When the bullet is at its highest point of its trajectory, it collides head on with the bob of the pendulum and gets embeded in the bob. After collision, if the pendulum moves through a maximum angleof 120^(@), then the value of .theta. is (g = 10ms^(-2))
